I am a newbies of this site. Please, help me to read the math expressions in "non-plain" text form like this:

$$a=\left(\sum_i y_i b^{x_i}\right) / \left(\sum_i b^{2x_i}\right)$$

What addin, application will help me to read this and other expressions in "normal" or professional (as msword mentions) form?

Thank you.

ADDED:

I saw this one:

And now I see this one: alt text

I have resolved this problem by using Google Chrome or Latex Composer add-on for Firefox and this editor

  • $\begingroup$ What does "normal" mean? If you need the $\TeX$ code behind, right click on any expression and click "Show Source". $\endgroup$ – J. M. is a poor mathematician Dec 5 '10 at 13:57

  • $\begingroup$ Can you attach a screenshot or picture of what you are seeing and what you would like to see instead? $\endgroup$ – Rahul Dec 5 '10 at 19:21
  • $\begingroup$ @Rahul Narain I have resolved this problem, see my updated question $\endgroup$ – igor Dec 5 '10 at 19:45

    $\begingroup$ You shouldn't have been seeing that in the first place! Can you try removing the LaTeX Composer plugin and doing a hard refresh (instructions here: en.wikipedia.org/wiki/…)? $\endgroup$ – Rahul Dec 5 '10 at 19:48
  • $\begingroup$ @Rahul Narain I got error message: Your browser does not support MathJax :(. $\endgroup$ – igor Dec 5 '10 at 19:55

    $\begingroup$ Wow, what version of Firefox are you using? $\endgroup$ – Rahul Dec 5 '10 at 19:58
  • $\begingroup$ @Rahul Narain latest (3.6.12)... I know this is a strange bug in FF: it shows that I am using (3.6.12), but some sites detects my browser version as less than 2.0...:( I am going to reinstall it. :) $\endgroup$ – igor Dec 5 '10 at 20:01
  • $\begingroup$ That is very strange! I'm afraid I'm out of specific ideas now. You could try going through the various troubleshooting steps listed at support.mozilla.com/en-US/kb/Basic%20Troubleshooting, particularly the one under "Make a new profile". $\endgroup$ – Rahul Dec 5 '10 at 20:15
  • $\begingroup$ Additionally... what OS are you on? $\endgroup$ – J. M. is a poor mathematician Dec 5 '10 at 21:00
  • $\begingroup$ @J. M. Windows XP $\endgroup$ – igor Dec 5 '10 at 22:14
  • $\begingroup$ Can you check other browsers you may have installed to see if those have the same problem? $\endgroup$ – J. M. is a poor mathematician Dec 6 '10 at 0:19
  • $\begingroup$ @J.M. On Google Chrome it works perfectly! $\endgroup$ – igor Dec 6 '10 at 0:44

You shouldn't need any plug-ins to render the code. Please make sure you have enabled Javascript (since MathJax is a JS library), and the cache is not corrupt (try clearing the cache).
